REI EDI: The Complete 2026 Vendor Guide
REI Co-op's EDI requirements, vendor expectations, and how outdoor brands can automate setup
REI Co-op is one of the most respected outdoor retailers in the US, operating more than 180 stores and a large ecommerce business at REI.com. Because REI is a member-owned cooperative, their vendor relationships tend to be more collaborative than a typical big-box retailer — but their operational expectations are no less rigorous. REI expects clean EDI, accurate ASNs, and strong alignment on product stewardship and sustainability standards.
For outdoor, camping, climbing, cycling, snow sports, and performance apparel brands, REI is both a meaningful sales channel and a credibility stamp. Meeting their EDI requirements is the first step.
Required EDI Documents
| Document | Name | Direction | Purpose |
|---|---|---|---|
| 850 | Purchase Order | REI to Vendor | PO for DC or drop ship |
| 855 | PO Acknowledgment | Vendor to REI | Line confirmation |
| 856 | Advance Ship Notice | Vendor to REI | Carton and pallet detail |
| 810 | Invoice | Vendor to REI | Billing document |
| 997 | Functional Acknowledgment | Both | Transaction receipt |
| 846 | Inventory Advice | Vendor to REI | Drop-ship stock |
| 860 | PO Change | REI to Vendor | PO modifications |
Vendor Requirements
REI's vendor manual emphasizes:
- ASN accuracy and on-time transmission
- GS1-128 carton labels with the correct AI fields
- On-time and in-full ship to the DC (Sumner, WA or Goodyear, AZ)
- Product stewardship compliance (chemical restrictions, materials disclosures)
- Accurate drop-ship inventory and ship SLA
REI is also known for deep product data requirements — your PIM needs to be clean before you can list, but that's a separate track from EDI.
Chargebacks and Risk
REI's vendor compliance program covers:
- Late or inaccurate ASN
- Carton label non-compliance
- Late or short shipment to DC
- Drop-ship late ship or missing tracking
- Packaging and sustainability violations
REI is less chargeback-aggressive than big-box peers, but fees still accumulate on repeat misses, and relationship damage is a bigger real cost.
Common Setup Traps
The most common trap is underestimating REI's ship-window discipline. REI plans tightly around seasonal launches, and arriving a week early or a week late can both cause receiving issues. Another trap: not keeping drop-ship inventory in sync, which results in oversells that directly damage REI member experience.
